Inconel 600 Plates for HFC-134a Reactors

HFC-134a is an excellent environment-friendly coolant that is widely used as the substitute of Freon. The HFC-134a reactors are the core equipment in the production process. Generally, the medium that flows through the tube side of the reactor include HF, HCl, Fluorohydrocarbon, and little amount of water, while the reacting temperature is at 350°C ~ 370°C. Inconel 600 plates (ASME SB-168 UNS N06600) are selected as the main internal material of tube side. Inconel 600 has excellent resistance to oxidation and carbonization at high temperatures. It has good resistance to dehydrated chlorine at medium temperature and considerable immunity to stress corrosion cracking induced by chloride ion.

An HFC-134a reactor for a 3000 MT (annual) capacity project. The internal wall of its tube side is made of Inconel 600 cladding plate.
